SanDisk’s X400 is the successor to the X300/X300s series and is aimed at the corporate/mainstream market segments. It can be seen as an improved combination of both previous drives as it has the 256-bit AES encryption of the S version of the X300 built in as standard. The X400 family features SanDisk’s 6th generation 15nm Triple Level Cell TLC NAND and just like the previous X300 uses SanDisk’s nCache technology where some of the NAND runs in SLC mode to bolster performance.
